Default Master cylinder question

Hate to sound like a no experience newbie but....

It appears the factory lines (from my donor Elky) plumb my master cylinder rear port (closest to firewall) into the rear brake line. I've always heard the rear port is for the front brakes. Supposedly it gets pressure first. Perhaps this is a way to try and bias more toward the lesser stopping rear drums? Comments?

On all cars I have worked on, the rear port goes to the rear brakes, and front port to front brakes. The proportioning of the pressure is handled by the prop valve, combination valve or whatever you have on your car. Not sure if that goes for all cars though.

And it's better to sound like a newbie, than to end up with brakes that don't work

Amen Olle. The only "stupid" question, is the one not asked!

I agree with Olle. All the GM cars and trucks I have been associated with have the rear resivoir going to the rear and the front to the front. With the rear being proprotioned to keep them from locking up before the front have a chance to operate.

Rear to rear and front to front makes sense.

There's no difference with Front left and Front right though, is there?

Both front brakes are on the same line down to the junction block on the frame. Doesn't matter which one goes where from the junction block and on. The rear line is a different dimension, so you can't really mix them up either.
